3.5.9 MIC-7 anionic system with chemical suppression and dialysis
This system requires the model 2.838.0110 of the 838 Advanced
Sample Processor.
The 838 Advanced Sample Processor is connected to an anionic IC
system with chemical suppression with 819 IC detector, 820 IC Separa-
tion Centre, 818 IC pump, 833 IC Liquid Handling Unit and 830 IC Inter-
face in accordance with Figure 37 using the 6.2141.190 remote cable.
and the 6.2134.090 RS232 cable.

838-specific settings in the «IC Net 2.3» program
The sequences of an automated IC analysis with prior dialysis can be
programmed in two different ways:
A) A sample is first prepared by dialysis for each analysis and this
sample is then chromatographically separated.
